[23] and BippyPhos-type ligands as a broad ligand class for C-N coupling reactions.[24-29] All of the ligands screened enabled coupling with aryl bromide 2a; in contrast, only BippyPhos-type ligands ... WebMar 18, 2024 · Among the ligands developed is BippyPhos. This ligand was originally designed to enable a coupling of primary amines with aryl halides. Further studies showed that the ligand has fairly broad utility for Pd-catalyzed C−N, C−O and C−C couplings. This review describes the various Pd-catalyzed applications involving BippyPhos as a …

WebMar 20, 2008 · We describe the efficient preparation of Bippyphos, 1. The key precursor to Bippyphos, 5, was prepared via a one-pot bromination of diketone 2 followed by alkylation with pyrazole and condensation with phenylhydrazine. Lithiation of 5 and trapping with di- tert -butylchlorophosphine afforded Bippyphos, 1.
